Abstract

PURPOSE:To improve the melting speed of the filler metal, and to secure the good penetration without causing the dripping of the molten metal, by so varying the reference value of the arcing voltage automatic controller, as to make the arcing voltage to be higher nearby the end portion of the swing motion of the torch. CONSTITUTION:When the electrode 12 is standing at the middle point of the swing motion, the contact 25 is closed and 26 is open, and the welding is carried out by the reference arcing voltage set in the first reference voltage setter 19. When the electrode 12 makes a swing motion and comes to the range of swing end being set in the range of end setter 23, the relay 22 is excited by the command of the arithmetic amplifier 21; hereby, the contact 25 is switched to open and 26 to close. As a result, the arcing voltage V1 being set in the first reference voltage setter 19, varies to the reference voltage V2 which is 0.5-5V higher than the value set in the second reference voltage setter 24. Thus, the arcing voltage is suitably controlled over through the swing pass, and the optimum TIG welding is carried out correspondingly to the position of the groove.
